How the Top Signal −10/−0.5 dB 50‑ohm coupler is used

  • Splits a single run of coax cable differentially, with the −10 dB coupler running to an inside antenna, and the −0.5 dB passthru running farther downline to other antennas, couplers, or splitters.
  • For in-building use with 50-ohm cell signal booster systems and ½‑inch, 400, or 240 coax cable terminated with N-male connectors.

Please note

  • Because of the signal loss (attenuation) involved, we recommend using a coupler only if you have strong outside signal.
  • Users with weak outside signal should consider purchasing multiple, independent cell phone signal booster systems instead of dividing the signal from a single booster.
